Hi there !
I've been building a gnome sorcerer (typical i know, but my last character was a gnome barbarian...) and I was changing my racial traits to get something that would fit the idea i had with the character, when I realized i had these racials bonuses: +2 saves vs illusion, +2 bonus vs fears, +2 bonus vs death effect.
How do I use these exactly, my DM wanted me to be 100% sure about it, even tough I was pretty sure they would stack together, according to the rule in the common terms: "The important aspect of bonus types is that two bonuses of the same type don’t generally stack. With the exception of dodge bonuses, most circumstance bonuses, and racial bonuses, only the better bonus of a given type works. Bonuses without a type always stack, unless they are from the same source."
Ex: If someone cast a phantasmal killer on me: It got the illusion part, the fear part and the death part, so it should give me +6.
Or as my DM think it might be used.
Ex: If someone cast the same spell I only benefit from my racial bonus once per roll since I take the highest bonus, so I'd only get +2.
